CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 344,693, dated June 29,1886.

Application filed April 19, 1886.

Serial No. 199,413. (No model.)

To all whom it may concern.-

Be it known that we, PEARY THRUSH and DANIEL WEBSTER AURA, citizens ofthe United States, residing at West Alexandria, in the county of Prebleand State of Ohio, have invented a new and useful Improvement inCar-Gouplings, of which the following is a specification.

Our invention relates to an improvement in car-couplings; and itconsists in the peculiar construction and combination of devices, thatwill be more fully set forth hereinafter, and particularly pointed outin the claim.

In the drawings, Figure 1 is a perspective view ofacar-couplingembodying our improvements, with the upper portion of the draw headpartly broken away. Fig. 2 is a vertical longitudinal sectional view.horizontal sectional view.

A represents the draw-head, in the lower side of which is formed a caseor chamber, B, which is opened at its rear end. In between the upper andlower walls of the chamber, at the rear end of the same,is j ournaled apair of guiding'sheaves, O, and on the lower end of a shaft, D, which isjournaled vertically in the draw-head and extends through the same, issecured a pulley or drum, E, to which a rope or cord, F, is secured. Theends of the said rope or cord extend rearwardly from the drum E and overthe sheave (land from thence pass outwardly through openings which aremade in the side walls of the chamber B, and are connected to the outerfree ends of pivoted jaws H. These jaws are pivoted between the lowerand the upper side of the drawhead upon pins I, which connect the saidupper and lower portions of the draw-head. Each jaw is provided with arearward-em tending arm, h, the said arms of the jaws diverging fromeach other, and with a forwardextending arm, h, which extends at aboutan angle of thirty degrees from the arm h, and is provided at its outerend, on its inner side, with a head or shoulder, if. The mouth of thedraw-head is concaved or rounded, as shown, so as to guide the barbedhead of the coupling link or pin K into the mouth of the draw-head, inorder to engage with the heads or shoulders of the pivoted jaws.

In the central portion, M, of the draw-head, between the top and bottomsides thereof, are secured flat springs N, the front ends of which arefree and bear against the inner sides of Fig. 3 is a the arms h of thepivoted jaws, thereby normally diverging the said arms h, and closingthe heads of the pivoted jaws together. By this construction it will bereadily understood that when the cars come together the coupling pin orlink having the barbed head It enters the draw-head and passes betweenthe shouldered heads of the pivotedjaws, and that the action of thesprings on the said pivoted jaws causes their heads to close toward eachother behind the barbed heads of the coupling pin or link, therebycoupling the cars together beyond the possibility of their becomingaccidentally detached.

In order to uncouple the cars it will be necessary to partly rotate thevertical shaft D, which is provided at its upper end with a hand wheelor crank for that purpose. When the said shaft D is turned, the drum Eis also rotated, thereby drawing in upon the cords or ropes F, anddrawing the rear ends of the pivoted jaws toward each other, thuscausing their headed ends h to diverge and release the head of thecoupling pin or link.

A car-coupling thus constructed is is not likely to get out of order.

Having thus described our invention, we claim The combination, with thedraw-head A, formed with a chamber, B, in its under side, sheaves O,journaled in the chamber, a vertical shaft, D, journaled vertically inthe draw- .head, a pulley or drum, E, mounted. on the shaft within thechamber, and a rope, F, secured to the drum and formed into twobranches, of the jaws H, pivoted in recesses between the lower and upperportions of the drawhead, and provided with rearwardly-extending arms h,to which the two ends of the rope F are attached, and forwardlyextending arms h, which extend at an angle to the arms h, and springs N,bearing against the inner side of the arms h, the pins I, which serve aspivots for the jaws, also providing connecting means for the upper andlower portions of the jaws, as and for the purpose set forth.

In testimony that we claim the foregoingas our own we have heretoaffixed our signatures in presence of two witnesses.
